How to get my laptop to detect multiple displays.

I have gone to display settings and clicked detect but it is saying it detects no other device. I have checked all connections. I have tried restarting my laptop. I have tried powering off the laptop and monitors then switching the monitors back on first, then the laptop.

My laptop has previously connected to these displays but I have been in another location and connected to a different monitor.

    Right click your Start Button and open Device Manager.

    Expand the 'Display Adapters' section.

    Use the built-in display troubleshooting and multi-monitor setup steps in Windows 11.

    1. Confirm Windows sees any external display at all
      1. Select Start > Settings > System > Display.
      2. Scroll to Multiple displays and select Detect.
      3. If nothing is found, reseat the video cable at both the laptop and monitor ends (unplug and firmly plug back in). A loose or poorly seated cable is a common cause.
    2. Check that the hardware can support more than one external monitor If only one external monitor ever works at a time, or none are detected:
      • Some display adapters (graphics cards) only support a single external monitor.
      • If the laptop has only one video output, it may only support one external monitor unless using:
        • A compatible docking station, or
        • A USB-C adapter that adds an extra video output.
      • If using a splitter, be aware it typically only duplicates a single signal and cannot create two independent displays.
    3. Rearrange and enable displays when they are detected Once Windows detects more than one display:
      1. Go to Start > Settings > System > Display.
      2. Under Rearrange your displays, select Identify to see which screen is which.
      3. Drag the display icons to match the physical layout, then select Apply.
      4. Under Multiple displays, choose how to use each monitor (for example, Extend instead of Disconnect this display).
    4. Try a graphics reset and restart If the setup previously worked and suddenly stopped:
      1. Press Windows logo key + Ctrl + Shift + B to reset the graphics driver.
      2. If that does not help, select Start > Power > Restart.
      3. If needed, shut down completely (Start > Power > Shut down) and power back on.
    5. If still not working
      • Verify that at least one external monitor works by itself with the laptop.
      • If one works but multiple do not, the graphics adapter or dock may not support more than one external display; check with the device or dock manufacturer.
      • If none work and all steps have been tried, use Feedback Hub to report the issue so it can be investigated further. See Open the Feedback Hub.
